Take That's Gary Barlow is helping to organise this year's Children In Need Rocks event.
"It's going to be the biggest artists of this decade all on one stage," he said.
The show, which will feature Lady Gaga, Coldplay and JLS, will take place at Manchester MEN arena on 17 November.
Proceeds from the 12,000 tickets will go to Children In Need.
He was speaking to Newsbeat's music reporter Greg Cochrane.
